Application December 28, 1944, Serial No. 570,087

3 Claims. 1

The invention has particularly to do with means for making it easy andcertain of maintaining a clean and sanitary bath tub, and itaccomplishes this by the means for carrying the water around the top ofthe tub, with nozzle means for discharging the water into the tub, butdischarging it on the wall thereof in such a manner that the wall iskept clean and free from Water and soap marks or lines.

I have also provided a detachable top rail or cover member havingcorrugated form to prevent the hand from slipping when a person isgetting out or getting into the tub.

I have shown in the accompanying drawings, one practical embodiment ofmy invention, which I will now describe.

Figure 1 is a top plan view, looking down into a bath tub embodying myinvention;

Figure 2 is a vertical, longitudinal sectional view through said tub,taken on the line 2-2 of Fig. 1;

Figure 3 is a fragmentary sectional view, showing how the top rail isattached to the top of the tub, and also showing the spacing of thenozzle means for discharging the water into the tub; and

Figure 4 is an enlarged cross sectional view taken on the line 4-4 ofFig. 3, showing the water channel and the nozzle construction.

Referring in detail to the drawings, the bath tub is designated 5, andit has formed or moulded around its upper edge a water channel 6, withpipe connection at l for connecting a supply of water thereto. ThisWater connection can be at any place and in any form and whereby hot andcold water can be directed into said water channel 6. A series of flangeelements areshown formed thereon, designated 8, and adapted to suppporta top rail or hood 9, having spaced lugs, as at 9', to fit over saidflange elements, as shown, whereby said top rail or hood is held inplace, and at the same time can be removed for any purpose.

I have shown a special water nozzle for connecting into said waterchannel 6, as indicated in Fig, 4, for the purpose of discharging thewater down over the inner wall of the tub, as indicated. This nozzlestructure has an attaching shank l0, which can be threaded or otherwisesecured in place, with an inside wall or bafile 2 I I which, with thebody 12 overlying said wall or bafile, converges at its lower edge withan inner lip portion [3, to form a restricted outlet opening at l4 forfOIClng water in a spray of width, instead of being round, so as tocover a considerable area of the inner Wall of the tub. It is intendedthat these nozzles will be sufficiently numerous, and of such spreadextent in the discharge of the Water, that the surface of the tub willbe covered and kept clean by the force of the water forced through saidnozzles.

I am aware that attempts have been made to provide a water channelaround the top of a tub with opening for shower purposes, when a personis in the tub, but my invention is not for Shower purposes, but for thepurpose of sanitation and easy cleaning of the inside of a bath tubwhenever water is turned on and discharged thereinto.

I am aware that changes in the details of construction and arrangementcan be made without departing from the spirit of my invention and I donot, therefore, limit the invention to this detailed showing, except asI may be limited by the appended claims.

I claim:

1. A bath tub having formed integrally around its top a water chamberwith means for connecting a source of water supply therewith, aplurality of discharg nozzles connected with said water chamber on theinner side thereof and directed downwardly on the inner sides of the tubproper, whereby to clean the same as well as to supply water to saidtub, said nozzle havin an elongated and restricted discharge opening togive increased force and spread to cover the inner surface of said tub.

2. A bath tub having formed integrally around its top a water chamberwith means for connecting a source of water supply therewith, aplurality of discharge nozzles adapted to be connected into said waterchamber on the inner side thereof and directed downwardly on the innerwall of the tub, said nozzles each having an inner wall forming a watertrap for retaining a quantity of water in said water chamber and saidnozzles, and through which Water must flow to the discharge opening ofsaid nozzle when the supply is directed into said chamber.

3. A bath tub having formed around its top REF RE CES CITE The followingreferences are of record in the file of this patent:
